How to use

Install the M.2 NVMe SSD into an available M.2 2280 slot on a compatible motherboard or laptop following the device manufacturer’s instructions. Ensure the system BIOS/UEFI is updated and configured to recognize PCIe Gen4/Gen3 NVMe storage. After physical installation, initialize and format the drive in the operating system, then install your OS, games or applications and use WD_BLACK Dashboard to monitor drive health and apply any firmware updates.

Recommendations

Use the SN770 in systems with PCIe Gen4 support to maximize sequential throughput; if your system is PCIe Gen3-only, the drive remains compatible but will operate at Gen3 speeds. Regularly check WD_BLACK Dashboard for firmware updates and enable any provided performance modes for gaming when sustained peak performance is required.
